Trypanotolerance in cattle and prospects for the control of trypanosomiasis by selective breeding
Revue Scientifique et Technique de l'OIE, 1990 Tsetse-transmitted trypanosomiasis is one of the major constraints on the expansion of the livestock and agricultural industries in Africa. The disease affects animals and man, with direct and indirect losses estimated in billions of dollars annually. Because of the phenomenon of antigenic variation, no vaccine is available.

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1992 L'épidémiologie de la trypanosomose chez les veaux de race trypanotolérante et l'influence d'un traitement font l'objet de deux études. La première consiste en un suivi parasitologique et clinique de 100 veaux, de la naissance à l'âge d'un an : les ...

Molecular Ecology, Volume 34, Issue 24, December 2025.ABSTRACT Cameroon Blackbelly sheep are a domestic breed of hair sheep from West/Central Africa. They are popular with small‐holder farmers in Cameroon as they are highly resilient to local environmental challenges and are prolific a‐seasonal breeders.

Parasite control and assessment of trypanotolerance
, 2014 The exploitation of resistance traits very much relies on the understanding of the mechanisms underlying trypanotolerance, their characterisation in the field, the identification of practical measures of trypanotolerance characteristics, the evaluation ...

Farmers’ perceptions on trypanosomosis and trypanotolerance character of the taurine Sheko
Tropical Animal Health and Production, 2011 In the humid and subhumid tropics, trypanosomosis is an economically important zoonotic protozoan disease of the commonly kept farm animal species and their wild relatives. For example, more than 20% of the humid western and southwestern Ethiopia, which is home to more than 14 million heads of cattle, is under varying levels of trypanosomosis risk. Our

Evolutionary Applications, Volume 17, Issue 6, June 2024.Abstract As an invaluable Chinese sheep germplasm resource, Hu sheep are renowned for their high fertility and beautiful wavy lambskins. Their distinctive characteristics have evolved over time through a combination of artificial and natural selection. Identifying selection signatures in Hu sheep can provide a straightforward insight into the mechanism

Signatures of positive selection in African Butana and Kenana dairy zebu cattle.
PLoS ONE, 2018 Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst African indigenous zebu cattle because of their high milk production.

Uncovering the architecture of selection in two Bos taurus cattle breeds
Evolutionary Applications, Volume 17, Issue 2, February 2024.Abstract Directional selection alters the genome via hard sweeps, soft sweeps, and polygenic selection. However, mapping polygenic selection is difficult because it does not leave clear signatures on the genome like a selective sweep. In populations with temporally stratified genotypes, the Generation Proxy Selection Mapping (GPSM) method identifies ...

Towards an understanding of genetic control of trypanotolerance
, 2013 Over the past few years, research at ILRI and by its partners has identified genomic regions controlling trypanotolerance in cattle and in mice. In mice many of the genes lying within these genomic regions have been identified, leading the way to ...
